CS4228集成電路（IC）的編解碼器規(guī)格書PDF中文資料

CS4228屬于集成電路（IC）的編解碼器。由凌云邏輯制造生產(chǎn)的CS4228編解碼器編解碼器是用于通過壓縮和解壓縮來轉(zhuǎn)換數(shù)據(jù)的半導(dǎo)體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲空間。某些編解碼器提供高達 32 位的分辨率，并且分別提供多達 6 個或 8 個模數(shù)轉(zhuǎn)換器和數(shù)模轉(zhuǎn)換器。除三角積分調(diào)制外，還有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 數(shù)據(jù)接口。

Description

The CS4228 codec provides two analog-to-digital and six digital-to-analog delta-sigma converters, along with volume controls, in a compact +5/+3.3 V, 28-pin SSOP device. Combined with an IEC958 (SPDIF) receiver (like the CS8414) and surround sound decoder (such as one of the CS492x or CS493xx families), it is ideal for use in DVD player, A/V receiver and car audio systems supporting multiple standards such as Dolby Digital AC-3, AAC, DTS, Dolby ProLogic, THX, and MPEG.

A flexible serial audio interface allows operation in Left Justified, Right Justified, I2S, or One Line Data modes.
